Collapsed shelless egg. The hen needs extra calcium to make her eggs have a strong shell. Unless her condition is treated, she will run the risk of getting an egg stuck and it could end up killing her or triggering a chronic reproductive infection.

Pry open the beak and give one whole tablet directly into her beak every day until her eggs are coming out with a strong shell. After they are back to normal, she can then go back to supplementing her calcium needs with oyster shell and/or layer feed.
